VAPOR-BURNER.

SPECIFICATION forming part of Letters Patent No. 269,083, dated December12, 1882.

Application filed August 14, 1882. (No model.)

To all whom it may concern Be it known that I, THOMAS D. McCon- MIGK, ofGanton,in the county of Stark and State of Ohio, have invented certainnew and useful Improvements in Vapor-Burners; and I do hereby declarethe following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itpertains to make and use it, reference being had to the accompanying'drawin gs,

which form part of this specification.

My invention relates to an improvement in vapor-burners; and itconsists, first, in combining in the supply-pipe through which the oilpasses to the burner an automatic shut-off and a screw plug or valve forcontrolling the flow of oil when the burner is first lighted; second, inthe supply-pipe having an automatic cut-off attached directly thereto,so that the expansion of the main supply-pipe itself shall operate'theautomatic cut-off; third, in

the combination of the main supply-pipe with an automatic cut-off whichis operated by the expansion of the supply-pipe itself, one end of therod or wire which forms the automatic cutolf being made to extendthrough the end of the supply-pipe, so-that it can be easily adj ustedso as to cut off the flow of oil sooner or later, as may be desired.

i The object of my invention is to place an automatic cut-off directlyin the main "supplypipe itself, and to connect this cut-off directly tothe pipe, so that the contraction of the pipe itself will operate thecut-off should the flame ofthe burner he accidentally extinguished,andthus prevent a continued flow of oil through the burner.

The accompanying drawing represents a burner, partly in section, towhich my invention is applied.

A represents a-vaponburner of'au y desired shape or construction thatmay be preferred, and B the supply-pipe through which the oil flows tothe burner. At any suitable point in this supply-pipe, beyond the reachof the vapor, is placed a plug or other suitable valve, (3, which is tocontrol the flow of oil in first starting the burner into operation.This plug,

when the burner is first being lighted, will be opened just far enoughto allow sufficient oil to flowpast it to fill the supply-pipe B and thedrip-cup which is used in connection w-ith all burners.

sary to let just suffieientflow past the valve to fill the drip-cup inthe usual manner. This plug-valve is then closed, and is not again useduntil the stove has to be again lighted. This plug or valve passesthrough a separate and distinct casting, E, ofits own, which is screwedor otherwise attached to the supply-pipe, soas to form a part thereof,and in this casting E' flow of oil, and when the burner is in use to.

open the hole, so as to allow the oil to flow freely through the burner.The supply-pipe B is made of some metal which is more expansible thanthe cut-off H, and which will expand and contract to a greater extentthan the cut-off. The upper end of this automatic cut-oft will have asmall slot cut in it, oritm'ay he provided with a head or handle, or beshaped in any way that fancy may dictate, so that at any time it can beadjusted by means of its screw-thread or otherwise so as to bring itsinner end nearer to or farther from the hole G. This automatic cut-offis not attached to or connected with any other device than either theend of the pipe itself or that portion of the burner'or other devicewhich is to be applied tothe pipe for the purpose of forming the end ofthe supply-pipe, and thus the automatic cut-off is dependent wholly uponthe expansion and contraction of the supplypipe itself for itsoperation.

The oil which remains in the supply-pipe since the last time the burnerwas used, or which has flowed past the plug or valve so as to fill thesupply-pipe, will be sulificient to keep up combustion after the burneris lighted until the parts have become thoroughly heated,'

and then when the supply-pipehas become heated sufficiently to expandlengthwise the automatic cut-ofi' will have its end lifted up- When thestove has been used the supply-pipe will always be more or less filledwith oil, and then it will only be neces-- keep up combustion.

ward away from the hole G, so as to allow the oil to flow freely intothe supply-pipe and Should the flames become suddenlyextinguished, thepipe will contract, and thus force the end of the automatic out-ofi'into the hole G again, so as to stop the flow of oil. By this means allaccidents arising from the overflow ot' the oil after the flames havebeen extinguished are prevented.

I am aware that a copper pipe having a rod attached to it has beenplaced inside of an iron supply-pipe, so that the expansion of thecopper pipe would cause the rod to act as a cut-off, and this Idisclaim. Myinvention differs from this in having the cut-off secured toand operated wholly by the supply-pipe itself without the aid of anyintermediate device.

Having thus described my invention, I

claim-- ply-pipe, and an automatic cut-offsecured to the supply-pipeitself for shutting offthe flow of oil after the flames have becomeextinguished, all combined substantially as shown.

2. The combination of a vapor-burner, a supply-pipe, an automaticcut-off that is attached directly to the pipe, a by-pass valve, and aperforated'diaphragm, substantially as described.

3. The combination of a vapor-burner, a supply-pipe, an automaticcut-off which is attached directly to the pipe, and a perforateddiaphragm, the upper end of the cutoff being made to extend through thepipe so that it can be adjusted, substantially as set forth.

In testimony whereotl afiix my signature in presence of two witnesses.
